It looks like the enumerator may have written "Elsie," then written "Alice" over it.

6.  Records of the Supervisors of the County of Delaware (online at the Delaware County NYGenWeb site; transcribed by Linda Ogborn):

BOARD OF SUPERVISORS, 1861 REPORT OF COMMISSIONERS OF EXCISE Delaware County, ss: I hereby certify the following to be a true copy of the Report of the Commissioners of Excise, amde to the Board of Supervisors for the year 1861. Dated December 21st 1861. B. F. Gerowe, Clerk of Board of Supervisors TO THE BOARD OF SUPERVISORS OF THE COUNTY OF DELAWARE: Pursuant to a resolution of your honorable body, at its annual meeting held in the month of Nov. 1861, "requiring the Commissioners of Excise of said County to report to your Board, at the next meeting thereof, the amount of fines and penalties collected by them, and the suits commenced since their last report, and of monies collected by them or their Attorney, during the last year, and of what disposition has been made of the same, and the settlement of actions commenced, and of judgments, and a detailed statement of how settled, and of all monies collected in the several towns and the names of the individuals licensed, and the towns where licensed, and the disposition made of such license monies," the undersigned respectfully report, that the following statement contains a full list of the names of the individuals licensed, the character of the licenses, the names of the towns wherein the persons licensed reside, the amount of the license money received, all which has been paid over to the County Treasurer and his receipts obtained therefor, to wit:   NAME STORE OR GROCERY PLACE OF RESIDENCE AMOUNT …       Charles J. Durfee Store & C Tompkins 30.00 …

Note:  It's not "& C", it's "&c", which is the old-fashioned abbreviation for "etc." — it does not mean "and C."
I bother to quote the item because it reinforces that Charles's middle initial was "J.," not "G."

7.  Tavern Keepers, 1797-1862, Delaware County, NY (online at the Delaware County NYGenWeb site; submitted by Shirley Houck):

1862... DCA-10.645 16-Jun 12-Nov Against Charles J. Durfee by D.D. Chamberline & Others Village of Cannonsville, Town of Tompkins Grocery in Village of Cannonsville, Town of Tompkins  DCA-10.646 19-May 12-Nov Against Charles J. Durfee by A.J. Farmer & Others Village of Cannonsville, Town of Tompkins Grocery in Village of Cannonsville, Town of Tompkins  DCA-10.647 16-Jun 12-Nov Against Charles J. Durfee by A.J.

Durfee by Wm. K. Owens & Others Village of Cannonsville, Town of Tompkins Grocery in Village of Cannonsville, Town of Tompkins

Again, I bother to quote this item to support our subject's middle initial as "J.," not "G."
